I've only very recently gotten interested in trying pixel art and I've been having issues finding answers to certain questions and I'm left having to analyze the sprite work I want to emulate and maybe guessing what their workflow was
For example, two things I'm looking at are 1.) the comic panels from EBA/ Ouendan and 2.) character sprites from AA. I can kind of tell the EBA comics are just downscaled from full-res art but I can't tell for sure if that's what they did for AA as well. It feels more likely for AA4, since that was the only one fully built from the ground up for the DS
